RESUMO

IgG4-related disease is a relatively new disease entity characterized by elevated serum IgG4 levels and marked infiltration of IgG4-positive plasma cells in lesions. Organ enlargement or nodular lesions consisting of abundant infiltration of lymphocytes and IgG4-positive plasma cells and fibrosis are seen in various organs throughout. We encountered a patient with an inflammatory pseudotumor of the rectum, which was histopathologically confirmed to be an IgG4-related disease. The patient was a 28-year-old woman who had constipation for 3 months. The endoluminal ultrasonography showed a lesion that was heterogeneous and low echogenic in lower rectum. The result of colonoscopic biopsy findings was of chronic proctitis with lymphoid aggregates. For a confirmative diagnosis, excision was performed. Histopathological examination represented plasma cell infiltration and fibrosis. Immunohistochemistry revealed prominence of IgG4-positive plasma cells and confirmed the diagnosis of IgG4-related disease. The patient is currently under observation on low-dose oral prednisolone without relapse.

RESUMO

PURPOSE: Limited traction has been an obstacle in the advancement of single incision laparoscopic cholecystectomy (SILC). Adequate retraction is necessary for safe performance of a cholecystectomy. In this study, we introduce our method for securing CVS for prevention of bile duct injury during performance of SILC and evaluated the effectiveness of the snake liver retractor. METHODS: A total of 148 patients who underwent needlescopic assisted SILC (nSILC) from February 2011 to February 2012 at Uijeongbu St. Mary's Hospital, Uijeongbu, Korea were analyzed. Patients were categorized into two groups: G roup I consisted of patients who underwent nSILC without use of a snake liver retractor from February 2011 to October 2011 (n=51) and group II consisted of patients who underwent nSILC using a snake liver retractor from October 2011 to February 2012 (n=97). Patient characteristics and operative outcomes were compared between groups in order to evaluate the effectiveness of use of a snake liver retractor during performance of SILC. RESULTS: There were no differences in age, sex, BMI, and history of previous abdominal surgery. However, more difficult surgeries for acute cholecystitis were performed in group II. Nevertheless, no differences in operative outcomes, such as operative time, rate of bile spillage, open conversion rate, intraoperative complication, and postoperative hospital stay were observed between groups. In addition, CVS identification time was rather shorter in group II, compared with group I. CONCLUSION: Results of this study showed that nSILC using a snake liver retractor can allow for achievement of CVS safely and for expansion of indication for SILC through improvement of exposure and obtaining adequate traction.
